I am new owner of SV83M mono blocks with dual
core option.My system is: CAL DELTA transport, CAL Sigma DAC(96/24) with
GoldPoint ladder type stepped attenuators (I dont like preamps in my system, so
I added Volume controls myself)TEK-LINE interconnects, Magnepan 2.7QR
speakers (I was using them with VTL MB-250 AMPS), Samadhi Acoustics "Natalia"
Speakers (I was using them with Jolida 102B amp, I sold this amp and speakers
were sitting in the bedroom noy being connected to anything), and Lowther
Fidelio ( I bought them specially for SV83M)

I was eager to do A/B comparison
between VTL and SV83M, I knew the comparison would be unfair, after all VTL's
were fully broken-in, mated with Magnepan, and 250W of tube triode power!!!!
Anyway I connected SV83M's to my system and gave it a first test. Right out of
the box the units sounded incredible!!!!! Of course I could not get them to
play loud, but at low listening level I heard 3-d Sound with a lot of details
and space between instruments, with wonderfull tone!!!! Wow!!!

Well, I
disconnected my Maggies and connected Samadhi speakers. Much more efficient then
Maggies (93dB vs 85dB) and I could not belive the sound!!!! It was magical, I
slapped on Mozart Piano Concerto No 17, turned it on and My daugther ran
downstars from her room to see who is playing her piano. It was like being
there, Piano sounded real!!! Well defined placement, size, and body.

Another
CD goes on, this tim it is Govi Seventh Heaven and the strings, drums,
cimballs all sounded real, no coloration, right
tempo!!! Unbelievable!!!!Next day came dissapointment. The music died, no
magic, no soundstage!!!!Well I went out and got myself XLO REFERENCE test
and Burn-In CD, and started burn-in process. According to XLO it can break-in
your system in quarter of normal required time. Well it did! But I was still
missing some High frequency details. After some thinking (I am an EE myself) I
decided to remove 100K resistors from the input to ground, and
Eurica!!! I got my details back and I got my magic!!!! Hooray!!!!

Needless
to say my VTL system had been sold! I am a happy camper with
SV83M's!!!The only other improvement I will make is I will replace my
Speakers with Lowther Fidelio (99dB efficiency), because my listening room is
Very large, and to get little higher than normal listening level is very
difficuilt with Natalia speakers and 5W amp.
